Which version of NFS ? Locking was introduced in version 4. However, locking even under NFS sucks. That warning in the SQLite FAQ isn't there because the writers of SQLite are bad programmers, it's there because locking under many NFS installations is not implemented properly. You may have an alternative of accessing your NFS drive as a shared drive. If you do this, then locking is implemented by the networking protocol, not by the driver of the space being shared. So if you have a way of sharing your NFS drive via SMB or AFS, or some other common space-sharing system, you might be able to get around the NFS problems completely.
